Non-Stop Number Fun!

Mrs. Ranney's new class has been exploring number sense!

The symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 are digits.

The even digits are 0, 2, 4, 6, and 8.
The odd digits are 1, 3, 5, 7, and 9.
Standard form: A way of writing numbers using digits

Expanded form: A way to write numbers by showing the VALUE  of each digit

Word form:  A way to write numbers using words

To practice with forms of a number, we found that we could use  the Clustr Map on our Blog!

 We have had 40,647 visitors to the blog since October, 2009.  We showed that number in all three forms!


We have reviewed skills with the hundred chart and odd and even digits by playing some games!

To practice with the hundred chart, several students played

Other students played manual Dog Bone!

Many students played Odd and Even with a partner.
The object of this game of strategy is to get 5 in a row,  vertically, horizontally, or diagonally.
A player who rolls an even number on the number cube  must cover any even number on the board.
A player who rolls an odd number on the number cube  must cover any odd number on the board.


Have you played Dog Bone? If so, how many bones could you place in one minute? 

Which numbers are easy to place and why?

What are some strategies you use to place your number quickly?
What other number games and activities 
have you enjoyed?

Another way to comment would be to choose a number of your own and show the standard, word, and expanded forms! 


  1. Dear Mrs. Ranney,

    I tried to send a post that asked if you put up posts on subjects. However, it never posted.

    I'm happy you put a post on about math because it is my favorite subject.

    I played dog bone and I can find all ten bones in one minute.

    The numbers that are easy to place are one hundred, ninety-nine, ninety-eight and the number all the way around the card. They are the easiest to place because they are easy to find.

    I memorize where the numbers are to place them quickly.

    I love playing mathletics because I like playing people from all around the world.


    1. @Lucas,

      Actually your comment about subject posts did get published. If you go back to the Welcome to Third Grade post, you'll see I also answered it!

      I'm glad that you enjoy math so much. We'll look forward to more math and other subject posts in the future!

  2. Dear Mrs. Ranney,

    I just finished playing Dog Bone. I got 9 bones in one minute! The number 1 was the easiest to find. Can't wait to play again tomorrow.


    1. @Anthony,

      Nice job of Dog Bone! Keep up the good work!

      Mrs. R♥nney

  3. Dear Mrs. Ranney,

    I got 10 dog bones in one minute! That was my goal for myself! I think the numbers 1-10 are easiest because they are in the top row so I know exactly where they are! I don't have any strategies to place numbers quickly. I just press on a random number and go up, down, or sideways.

    Here is the number seventeen in standard, expanded, and word forms:



  4. Dear Mrs. Ranney,

    I played Dog Bone and I got all ten bones in only 42 seconds! It was very easy for me, probably because I am in sixth grade, and I have already learned that stuff. I think the easiest numbers were 1-10 and 91-100 because they were right at the top and bottom. I remember in 2nd and 3rd grade, when I was doing probability, I really liked this game where we rolled the dice and saw what number appeared the most. Will you be doing that game this year?

    I'm going to do a complicated number, 1,987,542.

    One million, nine hundred eighty-seven thousand, five hundred forty-two.

  5. Dear Mrs. Ranney,

    I just played digital dog bone. It was fun. I got 9 bones in one minute, and 100 was the easiest number to find. In class I also played manual dog bone. I prefer digital because of the sound effects and timer.

    Which one does everyone else like better?


    1. Dear Colin,

      It's awesome how you almost got 10 bones.
      Great job!

      Your friend,

    2. @Gigi,

      Thanks for the nice compliment! See you tomorrow.

      Your friend,


  6. Dear Mrs. Ranney and class,

    I was very impressed by your number work. Being able to understand numbers in different forms is an important skill in our world.

    The Dog Bone game looks interesting. It combines chance, logical thinking and number knowledge in order to win. Like the game of Connect Four, I can see it is possible to block a player who nearly has five in a row so strategy is important.

    Well done, everyone. :)

    1. Dear Mr. Mannell,

      Thank you for visiting our blog and leaving a comment! We're so glad that you liked our post and the Dog Bone game.

      Many of us have played both manual and digital Dog Bone. Our times are getting faster!

      Are you having a great time in Australia? In what part do you live? We would love to hear more about Australia?

  7. Dear Mrs. Ranney

    Having fun at school? Digital Dog Bone is super fun! I can only get 10 or11 bones in one minute. I use many strategies. But I'll tell you one going down the tens parts of the hundred chart and finding the number.
    I think #1 and #100 are the easiest to find because they are at the beginning and end of the hundred chart. See you next week.

    Your friend,

  8. Dear Mrs. Ranney,
    School was really fun today! I liked the math lesson. What are we going to learn tomorrow? I cannot wait to find out!

  9. Dear Mrs. Ranney,
    I just played digital dog bone and I got 12 bones!
    It was much fun! When you play digital dog bone how many bones do you get? What is your favorite math game?
